Hello!
There are many theories about tooth problems. In ancient times many people believed that people could lose their lives to tooth problems, due to spreading infections throughout the body.
If you had lots of cavities or other tooth problems, and you do not get them cured, they will most likely fall out and infection could spread, which could be fatal.
I hope this helps!

Hope that helps.

They couldn't write with letters so they drew pictures. Hardly anyone knows anything about the writings of Native american literature.
